[Test-Equipment] Need Hitachi V212 scope schematic

[John King via Test-Equipment]

That is the problem, Miles. I don't know the resistor number on the board.  The resistors are numbered, but not labeled. I am sure I can change it out when I locate the resistor. I found it once before but did not make the change and then my schematic was lost. That is why I need the schematic. Thanks, Miles. 73, John, K5PGW

 I'm afraid I can't help you with a
 print of the schematic, BU
 
 If you are absolutely sure you have identified the defective
 resistor, clip
 it out. Replace it with a resistance substitution box (or a
 high-value pot).
 Set the substation box (pot) to its highest value. Set the
 horizontal
 control of the scope at mid-point, and dial the resistance
 down until the
 trace centers. Then replace the substitution box with a
 resistor of the same
 value.
